the nature of bulky phosphines used as ligands. As a result, conditions for involving the electron-deficient organoboron reagent—potassium pentafluorophenyltrifluoroborate—in the palladium-catalyzed cross-coupling with aryl bromides and arylchlorides were identified. It was demonstrated that the chosen conditions are appropriate for the reaction of K[C6F5BF3] with benzyl chloride and benzyl bromide

The first general examples of direct coupling of heteroaryl chlorides, especially substituted 2‐pyridyl chlorides which were previously found to be problematic, with electron‐deficient polyfluoroarenes are reported. Pd(OAc)2 associated with 3‐(dicyclohexylphosphino)‐2‐phenylindole L1 serves as the effective catalyst which allows the challenging direct coupling of heteroaryl chlorides and polyfluoroarenes

New reaction conditions for the direct arylation of polyfluoroarenes with aryl iodides have been developed. This reaction can be co-catalyzed by palladium=copper without ligands and exhibits excellent functional group compatibility.

the development of green and sustainable methods for direct C−H bond arylation of (hetero)arenes. In this context, here the infrared (IR) irradiation-assisted solvent-free Pd-catalyzed direct C−H bond arylation of (hetero)arenes was achieved. Several heteroaryl-aryl coupling reactions were described, also involving heterocycles commonly used as building blocks for the synthesis of organic semiconductors
